Hi all, I got my MBP a week ago and so far I love her. One thing I notice however is that the arrow keys seem to stick up higher than other keys on the board. Looking at them up close it appears that the small plastic piece that is on the bottom of all keys is dislodged on the left side of these keys, plus I seem a small loop shaped thing when looking under these keys. Is this normal? I realize it i might be cosmetic but I am concerned that lots of dirt might get under the keyboard.
